Incoloy 840 Nickel-based Alloy
Incoloy 840
Quantity:
Incoloy 840
Data grade: Incoloy 840 nickel-based alloy
United States grade: UNS S33400
Incoloy 840 Nickel-Based Alloy Overview:
1. Overview of Incoloy 840 (S33400) nickel-based alloy:
The Cr content in Incoloy 840 nickel-based alloys is usually 18-20% and the nickel content is 19-21%.
Incoloy 840 alloy is an austenitic stainless steel containing titanium and aluminum, containing enough chromium to form and maintain a sufficient scale of chromium oxide to protect it under high temperature conditions, and is more resistant to high temperatures than traditional chromium-nickel stainless steel such as 304; The higher nickel content makes the base have better oxidation resistance than the standard 18-8 stainless steel, and its oxidation resistance chamber is no less than higher grade alloys with temperatures up to 1900 degrees Fahrenheit (1038℃). .
Incoloy 840 alloy is ideal for the manufacture of electric heating tubes, automotive emission control systems and other high temperature resistant products.
